any desired number of sections or planks can be used to completely coveror close the door. The opposite post or frame A is provided with anangle-iron C, which also extends'the To a whom it may concern Be itknown that I, DANIEL G. BRINSER\' 9, citizenof the United States,residing at Eliza bethtown, in the county, of Lancaster and '5- State ofPennsylvania, have invented new and useful Improvements in Car-Doors, ofwhich the following isa specification.

My invention relates to improvements in car-doors, and pertains moreparticularly to that class known as grain-car doors.

" The object of my invention is to provide a grain-car door which ismore readily opened .when the-car is loaded with grain and there is agreat pressure of the grain against the I 5 doori i 1 Another object ofmy invention is to provide a door of this character in which the graincan be unloaded from the car from top or bottom of the door and one inwhich the unloading is readily regulated.

A still further object of my invention is to provide a more simple,cheap, and effective car-door than has heretofore been produced. In theaccompanying drawings, Figure 1 is a side view of a section of a car",showing my improved door applied thereto and showing the top boardremoved for unloading the grain from the car. Fig. '2 is a transversehorizontal sectional view ofFig. 1. Fig. 3 is an- 3 enlarged verticalsectional view showing the. sliding bolts and their supporting member.gig. 4; is a plan view of my im )rovedsliding o t. r

Beferring now to the drawings, A and A represent the post or frameworkaround the car-door, and which, as shown, consists of enlarged squaremembers giving the necessary strength. Thepost Ahas secured 'theretoonthe inside of the car, by means of-bolts or 4 screws, a cl1annelironB,which has.its wall resting against and secured to the post A, and theopposite wall 6 is slightly bent or flared outward, the purpose ofwhichwill be hereinafter more fully described, the distance or width of. theinner end of said channel-ironj being slightly wider than the thicknessof the door or planks of which the door is composed, whether made of onepiece or more. This channel-iron extends the full height of the 5door-frame, and thus it canbe' readily seen that her, 0, on the side ofthe post and secured "thereto by belts or screws 0. The other mGB'Ibber, C forming a part of the angle-iron .G, secured to the inside of thepost 'by means of bolts. 01' screws 0', and the said member extends outeven-with the member C and is formed integral or as a part thereoli. Thesaid member Cis provided at its oute'r'end with an angular memberD,which forms a socket D for the outer ends of the planks or sectiom 5 ofthe door to rest'in; The inner face of the member C is provid d'with aseries of horizontal recesses E, which are connected by narrow webs e,and extending through said webs are the bolts or screws 0' and'recessesextending 76 out through the member 0 Within said re-. cesses are thesliding bolts F, which are; of a. thickness a little less than the depthof therecess E, and thus it will be seen that the bolts are adapted tofreely slide therein between the in- 7 5 nor faces of the recesses andthe outer face of the postA'. The said bolts havetheir inner ends fof awidth equal to that of the recess, while their outer ends are reduced atf, and thus they are prevented from passing outward c through therecesses inthe mem ber C The lower faces of said bolts are also providedwith notches G, which are adapted to drop over 7 the web g, and thus thebolts are held in an outward position. The extreme outer ends 3 of thebolts are turned laterally, forming members F, by which the same may bedriven -inward and also to prevent the bolts from sliding too farinwardly.

The car-door proper, as shown, is made-of 9 a series of transverseplanks H,which are not connected at all; but said door could be made inone, two, or three sections and each section I be independentlyremovable. The bolts, as

hown in Fig. l of the drawings, are so arg ranged that there are twoopposite each plank; but each bolt is movable independent of the other.Tn the operation of my device the bottom plank is first inserted at anangle, placing one entire height of the door and has the one mem- 5 5L,

end into the channel-iron B, and the opposite end is then placed in thesocket 1):, carried by the angle-iron, and the bolts opposite the saidplank are drawn outward and firmly 5 hold the said plank in position,and as the car is filled with grain or other material the succeedingplanks are placed therein in the same manner, The tendency or weight ofthe grain is to force the said planks or sections outward,

A and itwill be'seen that by striking the lateral and removed whether itbethe top or bottom section.

i 29 Having thus described my invention, what I claim as new, and desireto secure by Letters Patent, is a 1. Acar-door. comprising outwardlyinde-' pendently movable planks, and independently- 2 5 sliding boltscarried by said door-frame for each plank.

2. The combination with a door-frame, of a door formed of independenthorizontal sections, means carried by one side of the doorframefor-receiving the ends of said sections,

and independent locking means for each section carried by the oppositeside of the frame.

3. The combinati'on'with a door-frame, of a door formed of independenthorizontal members, means carried by one side of the doorframe forreceiving the ends of said members,

and sliding bolts carried by the opposite side of the frame for holdingsaid members independent of each other; r

4;. The combination with a door-frame, of a bers, a vertically-arrangedmember carried by one side of the door frame and adapted to receive theopposite ends of said members, and

43 a series of sliding bolts carried by the opposite side of the framefor each member.

5. The combination with a door-frame, of a door formed of two or moreindependent horizontal.- members, a vertically-arranged mem.'

ber carried by one sideof the door-frame and adapted to receive the endsof said members. a vertically-arranged plate carried by the op- Iposite'side of the frame, and outwardly-sliding bolts carried by saidplate and adapted to i hold saidhorizontal members independent of 5 ingbolts carried by said plate, and adapted to door formed of independenthorizontal meman outward position.
